About COR


The Center for Outcomes Research (COR) was established in 1997 and is a national leader in health outcomes research methodology.  Jeffrey H. Silber, MD, PhD, who holds the Nancy Abramson Wolfson Endowed Chair of Health Services Research at the Children's Hospital of Philadelphia and is Professor of Pediatrics and Anesthesiology and Critical Care at the University of Pennsylvania Perelman School of Medicine and Professor of Health Care Management at the University of Pennsylvania Wharton School, has served as the Director since the center's inception.  Scott A. Lorch, MD, MSCE, Associate Professor of Pediatrics and Neonatology at the University of Pennsylvania Perelman School of Medicine is the Deputy Director of COR.  Orit Even-Shoshan, MS, is a founding member of the center and serves as the Associate Director.  Research investigators come from a wide range of clinical and academic disciplines at the Children’s Hospital of Philadelphia and the University of Pennsylvania.  These include pediatrics, neonatology, oncology, statistics, health care management, anesthesiology and critical care, general internal medicine, nursing and others.  

COR is one of seven Centers of Excellence for the Pediatric Quality Measures Program, a program established by the Centers for Medicare and Medicaid Services and the Agency for Healthcare Research and Quality upon congressional approval in 2009 of the Children’s Health Insurance Program Reauthorization Act.  The AHRQ-CMS CHIPRA Center of Excellence at the Children’s Hospital of Philadelphia was established in 2011 and aims to advance the field of pediatric quality assessment through innovative outcome and process measure development, the application of rigorous statistical methods for risk adjustment and disparities assessment and its expertise in using electronic health records to measure quality.

The National Quality Forum has endorsed the Failure-to-Rescue measure, developed by Dr. Silber in 1990, and additional quality metrics developed by COR researchers have been endorsed by the National Quality Forum and the Agency for Healthcare Research and Quality.  Two current areas of emphasis for the center are multivariate matching study design and neonatal outcomes research.
